Filed: 2020-08-19
Abstract: To provide a compact and thin digital holographic microscope capable of highly accurately performing color imaging by using white light.SOLUTION: Two AWGs are combined to demultiplex white light by the AWG as a demultiplexer and to reduce a full width at half maximum of each wavelength by the AWG as a band narrowing function member, so that coherence is enhanced. Then, a wavelength of a wide band emitted from a single white light source is multiplexed/demultiplexed, so as to singly acquire spectral characteristics of an object. Besides, a wavelength selection switch is arranged between the demultiplexer and the band narrowing function member, so as to allow a wavelength to be freely selected. Then, the spectral characteristics of the object can be minutely investigated. When wavelengths are selected and combined, an interference fringe of the plurality of wavelengths is formed, so that a color original image can be generated. Since an array waveguide type grating is used for a multiplexer/demultiplexer, combination with an optical waveguide can be performed, so as to configure the AWG and the optical waveguide into a single chip.SELECTED DRAWING: Figure 1
